Background		 involves: 129S4/SvJae * C57BL/6 * SJL
Find Mice Using the International Mouse Strain Resource (IMSR)
Mouse lines carrying:
Mirc3tm1.1Tyj mutation (1 available); any Mirc3 mutation (1 available)
♀ phenotype observed in females
♂ phenotype observed in males
N normal phenotype
mortality/aging
prenatal lethality, complete penetrance ( J:134861 )
• no homozygous mice are recovered; lethality is suggested to be result of interference of the neomycin cassette with expression of the Mcm7 gene (positional effect)
